This appears to be a question from a test bank for Tindall and Shi's America: A Narrative History. You can find the answer in Ch. 27 in a section entitled "Hoover in Control." the answer to this is 3. This can be found in the book and it also makes sense when you think about Hoover's own political philosophy. Hoover did not believe in the idea of the government simply giving money to low-income people. This would have gone against his belief in "rugged materialism."

Giving tax breaks to lower-income people would have been fine. Lower taxes go with conservative values and they reward poorer people who work. Hoover also took action against patronage, refused to support "Red hunts" and was personally liberal on racial issues. In addition to pushing for support for Howard University, he defended his wife's right to entertain the wife of Oscar DePriest, the first ever black Congressman from the North.
